TRANSMISSION-GEARING FOR MOTOR-VEHICLES.

State of Massachusetts, have invented certain new and useful Improvements in Transmission-Gearing for Motor-Vehicles, ofwhich the following is a specification.

` This invention relates to improvements in transmission and reversing gearing, and is particularly designed for use in connection with a motor-driven vehicle.

The object of the invention is to provide a simple, strong, and compactstructure, which may be manufactured quite cheaply and the parts which may have become worn or broken. A Jfurther object of the invention is to provide an improved means whereby the adjustment of the sliding gears usually employed in this type of gearing for effecting a change drawings, in whichof s eed may be quickly and easily made, togetlier with anovel means of locking said gears in their adjusted position.

- The inventionconsists of the novel features of construction and arrangement hereinafter more fully described, particularly pointed out in the appended claims, and clearly illustrated in the accompanying Figure 1 is a top plan sectional view taken on line a a of Fig. 2, showing. the general arrangement of parts embodyin the invention;

Fig. 2, a longitudinal sectiona view taken on line b b, Fig. 1.; Fig. 3, a transverse sectional view taken. on line c c of Fig. 2, and Fig. 4 a to planview.

eferrin now more particularly to the drawings, t e numeral 1 designates a casing formed of the two parts 2 2, bolted together in any well-known manner. The casing 1 is formed upon' oneof its ends with oppositelydisposed journal-bearings 3 3, arranged inl direct alinement. In t e bearings 3 3 are mounted the axle-tubes 5 5, carrying the stub-axles 7 7 and provided with the lbevelgears 8 8, meshing with the bevel-pinions 9 9,

mounted on the shaft l0, carried by the eX-.

ternal ring-gear 16, the wholeforming a com pensating vgear of well-known construction. At its op osite' end the casing 1 is formed with a journa -bearing4 for the reception of the Specification or' Letters Patent.

engine Or power shaft 6. Mounted on the inner squared end of the engine-shaft is'a bevel-gear 20, having the elongated cylindrical hub 35. l

The o posite Side walls of the casing are rovideci3 with .guide'ways 36, having the caring-surfaces 14. The numeral 37 desig.

nates a spider formed of the body portion 21 in the form of a square block, havinga cylindricalbore and mounted on the extended hub 35 of the bevel-gear 20, being retained thereon by means of the collar 22. The outer squared portion of the member 21 is seated in a correspondingiysquared portion of the casing ,1, asshown at 38, and thereby held from rotation. Thev member 21 is rovided with the two arms 13, formed at t eir outer ends with the enlarged portions 12, adaptedto work within the guideways 36. Mounted between the arms 13 13 oi' the spider 37 is a'square shaft 11, having its ends rounded, as shown at 39, and journaled in the enlarged portions" 12 of said arms. Slidably mounted on the shaft 11 is a large s ur- .which are mounted the -smaller graduated Spur-gears 17 and 18. A large bevel-gear 19 is keyed on the shaft 1 1 and meshes with and is driven from the bevel-gear 20 on the engine-shaft 6. 1

- From the foregoin description it will be seen that to eiiect a o anoe of speed the gear 15 is moved longitudinally of the shaft 11 until spur-gear 17 is Iin alinement with gear `16 vand the s ider 37 forwardly until said gear.

meshes, an we will now describe the'mechanism by whichthese two movements are accomplished simultaneously. y

A rod 23, operated 'bya suitable foot-lever or other means, (not shown ,)v extends intothe casing 1at 41. The inner end oi' said rod is reduced and passes through one of the arms 13, as at 24, and is provided with the curved 'swinging arm 25. The outer end of the arm is ierced to receive a stud 26 of the saddle-bliick 27, which is adapted to straddle the periphery of the spur-gear 15. It' the lOO rod 23be given a partial rotation. and at the same time moved longitudinally within the casingl, the arm 25 will swing to the dotted -position shown in Fig. 3, thereby moving the gears-15 17, and 18 transversely on the shaft -neete-d to e pull-rod 3l.

.11 and -the solider 37 will. move forwerdlv in 1 l its guides-rays until one ot tnespnrgeers 17 or 18 meshes Wim 'the freer 16 thus 'reducing l n J e; the speen thereot.

in' Fig. 2 of the. drewings .is illustreted e.

devies for looking the spider in any one of its adjliisted positions. 'li'lie squared portion 21 of the Snider. 37 is provided with e. plurality of note; livoted to the easing directly above the .member E1 is e. pewl 2S, hav-- inge pointed end adapted to seat in one of the notoires 2Q, being loelred therein bj; 'the action et' the lever Said lever 30 is `pivoted interniediete its ends to the easing 1, one end thereof extending into the easing and its opposite end outside of the easing end con- 'llie inner end of the lever is provided with e @ein portion @12; edepted to beer against the new. and lool; the 'sa-nie in one of notehe 29.

ln order to reverse the motion of the geering, We provide en auxiliary gear 32, mounted in the bitureeted end et e bell-erenk lever 33, pivot-ed to the easing 1 in slinernent. with the gear 16. The opposite end of the lever extends outside ofthe easing end is eonneet ed to en operating-rod 34, eetueted from e hand-lever et the side ol' the oer. (Not. shown.) The operation of the reversing is accomplished as follows: The rod 23 is given e partial rotation, which nieves gear 15 trensw'erselj.vr on the shaft 11, until the sniell spur-gear 1.8 is in alinernentwith the ringgear 1 6. A pull on rod 3e then throws spurgeer 32 in between the gears 16 and 18, and the motion of said gear-Wheel 16 is reversed.
